Directly coupled slow speed wind turbine alternators. The application of directly coupled slow speed generators to horizontal and vertical axis wind turbine systems of medium and large power rating. Stage 2: Preliminary design

Abstract

This report describes the results of a preliminary design study of directly coupled wind turbine generators and follows the earlier pilot study undertaken by NEI-IRD in 1988. The study considers a number of detailed aspects of the electrical, mechanical and thermal design of these slow speed machines. It is shown that there are a number of conflicting requirements to the design, including the need to minimise generator weight and the need to minimise its cost and maximise its efficiency. Cost estimates are given for a number of vertical axis generator designs and the dependency of cost upon generator diameter and number of poles is discussed. Further effort is required to establish preferred designs on the basis of weight, cost and efficiency trade-offs. Other recommendations for further work are also made. (author).
